What are your 2 greatest qualities and 2 biggest flaws?

This pregunta pops up in job interviews a lot but let's answer honestly here.

So I've been told that 1. I'm selfless, I'm thoughtful and think about other people's needs before mine. 2. I'm open minded, I pass little judgement, I'm against discrimination but still try to see where other people are coming from, even if it's say racist as hell.

Flaws... 1. I'm self-conscious, need reassurance most of the time 2. I always go back to what I know is a nuisance to me, repeatedly making the same mistakes and end up a mess
